How to add google places autocomplete to xcode with swift (tutorial)
提问by Frederik J?rgensen
I want to add google places autocomplete to xcode with swift, so users can search on a city and press enter, so should the app show that city on the map.
我想用swift将谷歌地点自动完成添加到xcode，这样用户就可以搜索一个城市并按回车键，所以应用程序应该在地图上显示那个城市。
I′m using google maps, so it has to be connected to that map and the search bar would i like to have in the navi-bar (just above the map)
我正在使用谷歌地图，因此它必须连接到该地图，并且我希望导航栏中的搜索栏（地图正上方）
Does anyone know a good tutorial to do that??
有谁知道一个很好的教程来做到这一点？

Not exactly tutorials, but there are a few resources on Github, with people providing libraries and code samples to achieve what you're asking for.
不完全是教程，但 Github 上有一些资源，人们提供库和代码示例来实现您的要求。
- SPGooglePlacesAutocomplete (https://github.com/spoletto/SPGooglePlacesAutocomplete) is very popular and has many features, but it's written in Objective-C
- iOS Google Places Autocomplete (https://github.com/watsonbox/ios_google_places_autocomplete) is more recent, written in Swift, and also contains some examples.
- lots of others...
- SPGooglePlacesAutocomplete ( https://github.com/spoletto/SPGooglePlacesAutocomplete) 非常流行并且有很多功能，但它是用 Objective-C 编写的
- iOS Google Places Autocomplete ( https://github.com/watsonbox/ios_google_places_autocomplete) 是更新的，用 Swift 编写，还包含一些示例。
- 很多其他人...
Even without proper tutorials, you can still check out these libraries and understand how their code works to get some inspiration if you want to write your own components.
即使没有合适的教程，如果您想编写自己的组件，您仍然可以查看这些库并了解它们的代码如何工作以获得一些灵感。
As a sidetone, Google also has this page, but it's not a dedicated tutorial for iOS apps, just some useful explanations of how their API works: https://developers.google.com/places/documentation/autocomplete#examples
顺便说一句，Google 也有这个页面，但它不是 iOS 应用程序的专门教程，只是对其 API 工作原理的一些有用解释：https: //developers.google.com/places/documentation/autocomplete#examples

For Swift 3:
对于 Swift 3：
1- Select your podfile and type : pod 'GooglePlaces'
1- 选择您的 podfile 并输入：pod 'GooglePlaces'
2- In the appDelegate, add your API Key :
GMSPlacesClient.provideAPIKey("YOUR KEY")(Import the GooglePlaces)
2- 在 appDelegate 中，添加您的 API 密钥：（
GMSPlacesClient.provideAPIKey("YOUR KEY")导入 GooglePlaces）
3- Use this code in your viewController that contains the googleMap:
3- 在包含 googleMap 的 viewController 中使用此代码：
// This code snippet demonstrates adding a
// full-screen Autocomplete UI control
import UIKit
import GooglePlaces
class ViewController: UIViewController {
// TODO: Add a button to Main.storyboard to invoke onLaunchClicked.
// Present the Autocomplete view controller when the button is pressed.
@IBAction func onLaunchClicked(sender: UIButton) {
let acController = GMSAutocompleteViewController()
acController.delegate = self
present(acController, animated: true, completion: nil)
}
}
extension ViewController: GMSAutocompleteViewControllerDelegate {
// Handle the user's selection.
func viewController(_ viewController: GMSAutocompleteViewController, didAutocompleteWith place: GMSPlace) {
print("Place name: \(place.name)")
print("Place address: \(place.formattedAddress)")
print("Place attributions: \(place.attributions)")
dismiss(animated: true, completion: nil)
}
func viewController(_ viewController: GMSAutocompleteViewController, didFailAutocompleteWithError error: Error) {
// TODO: handle the error.
print("Error: \(error)")
dismiss(animated: true, completion: nil)
}
// User cancelled the operation.
func wasCancelled(_ viewController: GMSAutocompleteViewController) {
print("Autocomplete was cancelled.")
dismiss(animated: true, completion: nil)
}
}

You can try one for wrapper to implement Autocompletion for Place API with Google:
您可以尝试使用一个包装器来使用 Google 实现 Place API 的自动完成功能：
https://github.com/mrugrajsinh/MVAutocompletePlaceSearchTextField
https://github.com/mrugrajsinh/MVAutocompletePlaceSearchTextField
Its very simple drop-in control and subclass of UITextFieldso using by binding Class with simple UITextFieldyou can achive Auto completion dropdown similar as Uberand many popular app does.
它非常简单的插入控件和UITextField 的子类，因此通过将 Class 与简单的UITextField绑定使用，您可以实现与Uber和许多流行应用程序类似的自动完成下拉菜单。

For anyone thinking hey lets implement google maps api in my iOS app. This is so fun and easy ... there is a HUGE drawback.
对于任何认为嘿让我们在我的 iOS 应用程序中实现谷歌地图 API 的人。这非常有趣和容易......有一个巨大的缺点。
The Google Places API for iOS enforces a default limit of 1?000 requests per 24 hour period. If your app exceeds the limit, the app will start failing. Enable billing to get 150?000 requests per 24 hour period.
适用于 iOS 的 Google Places API 强制执行每 24 小时 1?000 个请求的默认限制。如果您的应用程序超出限制，应用程序将开始失败。启用计费以每 24 小时获得 150?000 个请求。
How quickly do you think the limit will be reached in a free or freemium app? Love the part where they say hey your app will start failing.
您认为免费或免费增值应用程序会以多快的速度达到限制？喜欢他们说嘿您的应用程序将开始失败的部分。
Read carefully the usage and terms of service.
仔细阅读使用和服务条款。

I also created a library to make these simple request without including any framework of third party library. You can also maintain cache for Autocomplete with the library.
我还创建了一个库来进行这些简单的请求，而不包含任何第三方库的框架。您还可以使用库维护自动完成的缓存。
To use to library follow these steps : -

GoogleApi.shared.callApi(input: input) { (response) in
if let results = response.data as? [GApiResponse.Autocomplete], response.isValidFor(.autocomplete) {

Since the question was asked, Google has added UI elements to the iOS SDK for this sort of workflow. Check out the documentation.
自从提出这个问题以来，Google 已将 UI 元素添加到 iOS SDK 以用于此类工作流程。查看文档。
